HOW DO WE STOP RELEASING CO2 FROM SAGD?

Burn the asphaltene that were removed at the SAGD Facility and inject the flue gas into the reservoir.

The asphaltenes were going to be burned someplace else anyway, so that reduces someone else’s emissions by about 470 kg CO2 per barrel of dilbit produced.

85% of the fuel value of asphaltenes is required to get the bitumen out of the ground.

The natural gas that would no longer have to be burned and this would save 87 kg CO2 per barrel of bitumen produced.

If the flue gas is sequestered underground, there will be no CO2 release per barrel of production, and 15% of the heat from the asphaltene burning will be used to make heat for the asphaltene removal process and clean electric power.

BEST®¹ ASPHALTENE COMBUSTION PROCESS

Heat balance showed that asphaltene combustion would be at about 3,690°C. (ΔH of -393.4 vs -111.4 kJ/mol heat of combustion)

Needed to add water to cool the combustion. Found that enough additional water to make a 3:1 steam to oil ratio would cool the combustor down to about 1,230°C. (Typically 1,000-3,000°C)

Generate clean HP Steam with flue gas heat from 1,230ºC down to about 275ºC. First pass H&MB shows that about 341 t/hr of HP Steam can be produced after generating about 595 tonnes of HP Steam in the combustor, and enough hot diesel fuel for the Asphaltene Stripper Reboiler (only hot oil user in complex) in the first part of the Flue Gas Effluent Cooler.

1 set of vessels, 4 heat exchanger services, and 1 turbine service is all that is required.

LONG TERM PROJECTION

With very few asphaltenes in DAB®¹ Oil and most of it being converted to transportation fuels (jet, diesel, and automotive), and no CO2 emissions upon production, environmentalists will want every refinery to use DAB®¹ Oil.

Since the DAB®¹ Oil can be transported by pipeline it can be transported to the refinery from the SAGD Producer using only clean electricity (nuclear, hydroelectric, solar, wind or produced in the BEST®¹ Asphaltene Combustion Process).

Gasoline, Diesel, and Jet Fuel produced from DAB®¹ Oil will have a lower carbon footprint than any others.

With no CO2 emissions on production, and little to no asphaltenes to be burned elsewhere, even Canadian environmentalists should support using this oil all over North America.

Usually the Pumps for the high pressure solvent circulation were ordered as soon as possible as they had a long lead time for delivery. Ideally they would be ordered right after the process design was completed. This is for a 30,000 barrel/day design.

The most recent 20 barrel/day plant was designed, constructed, and started up in less than 12 months.

Our 25 barrel/day demonstration unit would take 12-15 months after we received the money for the process design.
